Neon (2)

Neon (2)

Last updated Apr 23, 2026 is a fully managed serverless PostgreSQL. It separates storage and compute to offer modern developer features, such as serverless, branching, and bottomless storage.

Note

You can connect to Neon using Hyperdrive (recommended), or using the Neon serverless driver, @neondatabase/serverless. Both provide connection pooling and reduce the amount of round trips required to create a secure connection from Workers to your database.

Hyperdrive can provide the lowest possible latencies because it performs the database connection setup and connection pooling across Cloudflare's network. Hyperdrive supports native database drivers, libraries, and ORMs, and is included in all Workers plans. Learn more about Hyperdrive in How Hyperdrive Works.

To connect to Neon using Hyperdrive, follow these steps:

1. Allow Hyperdrive access

You can connect Hyperdrive to any existing Neon database by creating a new user and fetching your database connection string.

Neon Dashboard

Go to the Neon dashboard ↗︎ and select the project (database) you wish to connect to.
Select Roles from the sidebar and select New Role. Enter hyperdrive-user as the name (or your preferred name) and copy the password. Note that the password will not be displayed again: you will have to reset it if you do not save it somewhere.
Select Dashboard from the sidebar > go to the Connection Details pane > ensure you have selected the branch, database and role (for example, hyperdrive-user) that Hyperdrive will connect through.
Select the psql and uncheck the connection pooling checkbox. Note down the connection string (starting with postgres://hyperdrive-user@...) from the text box.

With both the connection string and the password, you can now create a Hyperdrive database configuration.

2. Create a database configuration

To configure Hyperdrive, you will need:

The IP address (or hostname) and port of your database.
The database username (for example, hyperdrive-demo) you configured in a previous step.
The password associated with that username.
The name of the database you want Hyperdrive to connect to. For example, postgres.

Hyperdrive accepts the combination of these parameters in the common connection string format used by database drivers:

postgres://USERNAME:PASSWORD@HOSTNAME_OR_IP_ADDRESS:PORT/database_name

Most database providers will provide a connection string you can directly copy-and-paste directly into Hyperdrive.

To create a Hyperdrive configuration with the Cloudflare dashboard:

In the Cloudflare dashboard, go to the Hyperdrive page. Go to Hyperdrive ↗
Select Create Configuration.
Fill out the form, including the connection string.
Select Create.

To create a Hyperdrive configuration with the Wrangler CLI:

Open your terminal and run the following command. Replace <NAME_OF_HYPERDRIVE_CONFIG> with a name for your Hyperdrive configuration and paste the connection string provided from your database host, or replace user, password, HOSTNAME_OR_IP_ADDRESS, port, and database_name placeholders with those specific to your database:

sh npx wrangler hyperdrive create <NAME_OF_HYPERDRIVE_CONFIG> --connection-string="postgres://user:password@HOSTNAME_OR_IP_ADDRESS:PORT/database_name"

This command outputs a binding for the Wrangler configuration file:

jsonc { "$schema": "./node_modules/wrangler/config-schema.json", "name": "hyperdrive-example", "main": "src/index.ts", "upload_source_maps": true, // Set this to today's date "compatibility_date": "2026-10-27", "compatibility_flags": [ "nodejs_compat" ], // Pasted from the output of `wrangler hyperdrive create <NAME_OF_HYPERDRIVE_CONFIG> --connection-string=[...]` above. "hyperdrive": [ { "binding": "HYPERDRIVE", "id": "<ID OF THE CREATED HYPERDRIVE CONFIGURATION>" } ] }

```toml "$schema" = "./node_modules/wrangler/config-schema.json" name = "hyperdrive-example" main = "src/index.ts" upload_source_maps = true # Set this to today's date compatibility_date = "2026-10-27" compatibility_flags = [ "nodejs_compat" ]

[[hyperdrive]] binding = "HYPERDRIVE" id = "" ```

Note

Hyperdrive will attempt to connect to your database with the provided credentials to verify they are correct before creating a configuration. If you encounter an error when attempting to connect, refer to Hyperdrive's troubleshooting documentation to debug possible causes.

3. Use Hyperdrive from your Worker

Install the node-postgres driver:

npmyarnpnpmbun

npm i pg@>8.16.3

yarn add pg@>8.16.3

pnpm add pg@>8.16.3

bun add pg@>8.16.3

Note

The minimum version of node-postgres required for Hyperdrive is 8.16.3.

If using TypeScript, install the types package:

npmyarnpnpmbun

npm i -D @types/pg

yarn add -D @types/pg

pnpm add -D @types/pg

bun add -d @types/pg

Add the required Node.js compatibility flags and Hyperdrive binding to your wrangler.jsonc file:

{
    // required for database drivers to function
    "compatibility_flags": [
        "nodejs_compat"
    ],
    // Set this to today's date
    "compatibility_date": "2026-10-27",
    "hyperdrive": [
        {
            "binding": "HYPERDRIVE",
            "id": "<your-hyperdrive-id-here>"
        }
    ]
}

compatibility_flags = [ "nodejs_compat" ]
# Set this to today's date
compatibility_date = "2026-10-27"

[[hyperdrive]]
binding = "HYPERDRIVE"
id = "<your-hyperdrive-id-here>"

Create a new Client instance and pass the Hyperdrive connectionString:

// filepath: src/index.ts
import { Client } from "pg";

export default {
    async fetch(
        request: Request,
        env: Env,
        ctx: ExecutionContext,
    ): Promise<Response> {
        // Create a new client instance for each request. Hyperdrive maintains the
        // underlying database connection pool, so creating a new client is fast.
        const client = new Client({
            connectionString: env.HYPERDRIVE.connectionString,
        });

        try {
            // Connect to the database
            await client.connect();

            // Perform a simple query
            const result = await client.query("SELECT * FROM pg_tables");

            return Response.json({
                success: true,
                result: result.rows,
            });
        } catch (error: any) {
            console.error("Database error:", error.message);

            return new Response("Internal error occurred", { status: 500 });
        }
    },
};

Note

When connecting to a Neon database with Hyperdrive, you should use a driver like node-postgres (pg) or Postgres.js to connect directly to the underlying database instead of the Neon serverless driver ↗︎. Hyperdrive is optimized for database access for Workers and will perform global connection pooling and fast query routing by connecting directly to your database.

To connect to Neon using @neondatabase/serverless, follow these steps:

You need to have an existing Neon database to connect to. Create a Neon database ↗︎ or load data from an existing database to Neon ↗︎.
Create an elements table using the Neon SQL editor. The SQL Editor allows you to query your databases directly from the Neon Console.

sql CREATE TABLE elements ( id INTEGER NOT NULL, elementName TEXT NOT NULL, atomicNumber INTEGER NOT NULL, symbol TEXT NOT NULL );

Insert some data into your newly created table.

sql INSERT INTO elements (id, elementName, atomicNumber, symbol) VALUES (1, 'Hydrogen', 1, 'H'), (2, 'Helium', 2, 'He'), (3, 'Lithium', 3, 'Li'), (4, 'Beryllium', 4, 'Be'), (5, 'Boron', 5, 'B'), (6, 'Carbon', 6, 'C'), (7, 'Nitrogen', 7, 'N'), (8, 'Oxygen', 8, 'O'), (9, 'Fluorine', 9, 'F'), (10, 'Neon', 10, 'Ne');

Configure the Neon database credentials in your Worker:

You need to add your Neon database connection string as a secret to your Worker. Get your connection string from the Neon Console ↗︎ under Connection Details, then add it as a secret using Wrangler:

sh # Add the database connection string as a secret npx wrangler secret put DATABASE_URL # When prompted, paste your Neon database connection string

In your Worker, install the @neondatabase/serverless driver to connect to your database and start manipulating data:npmyarnpnpmbun

npm i @neondatabase/serverless

yarn add @neondatabase/serverless

pnpm add @neondatabase/serverless

bun add @neondatabase/serverless

The following example shows how to make a query to your Neon database in a Worker. The credentials needed to connect to Neon have been added as secrets to your Worker.

```js import { Client } from "@neondatabase/serverless";

export default { async fetch(request, env, ctx) { const client = new Client(env.DATABASE_URL); await client.connect(); const { rows } = await client.query("SELECT * FROM elements");

    return new Response(JSON.stringify(rows));
},

}; ```
